Title: Inter-network routing control system
Inventor: MAEDA ATSUSHI
IPC: H04L12/46
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To prevent the overflow of a reception queue and to keep the routing performance by making a reception driver transfer its received packet to a protocol processing part via a scheduler, when the packet is addressed to the driver itself or transfer the received packet directly to the protocol processing part by a function call, when the packet is not addressed to the driver itself. SOLUTION: A router 10 receives a packet from a network 181 via a reception driver 161 and sends it to a packet distribution part 151 of a routing control part 15. The part 151 decides whether the packet is addressed to the router 10 by the address of the packet destination. When the packet is addressed to the router 10, the part 151 selects a method of transfer ring the packet to a protocol processing part 12 via a scheduler 13. When the packet is not addressed to the router 10 and when a fragment flag 152 exists, the packet is transferred to the part 12 via the scheduler 13. Thus, the load applied to the router 10 due to the packet, that is not addressed to the router 10 itself, can be prevented.

Abstract: PURPOSE:To increase volume efficiency by forming a part, which is in contact with an adhesive, of a container side wall so as to have a smaller inclination angle than the contact angle of the liquid adhesive to the horizontal. CONSTITUTION:A lead-acid battery is fabricated by bonding a battery container 1 in which power generating elements 5 are accommodated and a battery cover 2 with a liquid adhesive 3.

Title: Electron gun structure for color picture tube
Inventor: KOMORO HIDEMASA
IPC: H01J29/50
Filed: 1984-02-24
Abstract: PURPOSE:To obtain the always good focusing performance with no obstruction to mass production by providing a slit on the bent part of a correction electrode which separates and corrects an electron lens inside a cup-shaped electrode. CONSTITUTION:A slit 21 is provided on the bent part of a correction electrode 2. In this way, when pressing and welding, even if the force is applied so as to somewhat extend the external distance of the bent parts on both ends of the correction electrode 2, the neighborhood of the bent spots is easy to be bent so that stress is absorbed due to deformation of the space from the bent part to the pressing and welding spot while the position of the part to generate the function of separating and correcting an electrode lens in the middle of the neighboring electron beam passage holes hardly differs from the regular case. Accordingly, the lowering of the lens function can be checked thus extremely improving mass production.

Title: Liquid crystal display device
Inventor: MIZUNO YOSHIHIRO
IPC: G02F1/1335
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To enhance the utilization efficiency of light with simple constitution and to realize aimed color expression by providing a 2nd polarizing means between a liquid crystal function element means and a liquid crystal panel and irradiating the liquid crystal panel only with a light component in a polarization direction orthogonal to the polarization direction of a 1st polarizing means. SOLUTION: By impressing driving voltage, the liquid crystal function element means 3 generates parallel fringes constituted by the difference of refractive index. The light made incident on the means 3 is diffracted to irradiate the liquid crystal panel 1 by receiving the parallel fringes, so that color display is realized. By applying constitution that the 1st polarizing means 2 has the polarization direction to be parallel or orthogonal to the parallel fringes generated by the means 3, the polarization direction of zero-order light shows the same direction as that of the 1st polarizing means 2 and the polarization direction of 1st-order diffracted light shows the direction orthogonal thereto. Thus, the zero-order light is cut by the 2nd polarizing means 5 having the polarization direction orthogonal to that of the 1st polarizing means 2 and the aimed color expression is realized.

Abstract: PURPOSE: To execute optical connection between a basic bound mode and a clad mode by forming slight bending with spatial periodicity in an optical fiber. CONSTITUTION: Light is leaked from the fiber to its protecting coat by mode connection and orientation distribution which is indicated by arrows 31 and 32 by slight bending where a surface with fine lines is formed in a proper clamp condition and a proper fine line pitch. Moreover, the light is leaked to the inside of an upper side biting material 23 and leakage most efficiently occur at a part where a coat indicated by the arrow 33 is directly brought into contact with a connection element. In the fine line surface 60a which cooperates with the surface without the fine line of the connection element 64, light lead from the fiber 51 where slight bending is formed is drawn into the optical connection element 64 where a paralled conical reflection surface 63a is provided.  The incidence of light occurs in conflicting process using fine line structure 60b and the conical reflection surface 63b. Thus, a non-penetrating tap means the light incidence and light drawing to/from the fiber of the bound mode consisting of a core which is provided with a high refracting index.
